Answer:
C) CA=40
Step-by-step explanation:
2y/(2y+4)=(2y+6)/4y
cross multiply
8y²=4y²+20y+24
4(2y²)=4(y²+5y+6)
divide both sides by 4
2y²=y²+5y+6
y²-5y-6=0
(y-6)(y+1)=0
So the answer must be either 6 or -1. Since it can't be a negative number, it must be 6.
CA=2(6)+4+4(6)
CA=12+4+24
CA=40
Answer:
Step-by-step explanation:
The person I sent it to couldn't see it either. I'm going to take a chance and say the Chord (AB) and the Tangent line form a 50 degree angle. If this is incorrect, I won't know, from the diagram, what else to try.
If I'm right then <OAB = 40 degrees because 90 - 50 = 40 because <AOC is a right angle (property of radii and tangents).
<ABO also = 40 (the triangle is isosceles by two legs being radii).
That means that BOA = 180 - 40 - 40 = 100
Answer:
C. No, because 11.34 < 12
Step-by-step explanation:
3.14 + 4.12 + 4 has to be greater than or equal to 12
solve the equation
3.14 + 4.12 + 4 >= 12
7.26 + 4 >= 12
11.26 >= 12 is false
I don't know why it says 11.34 because the numbers don't add up, so I'll assume that there is a typo somewhere.
Answer:
25%
Step-by-step explanation:
25 divided 100 = 0.25
